Two of that magnets will make electrical contact and activate an IR led, the IR led will activate a phototransistor, and the phototransistor will activate a transistor and the transistor will activate a led and a volt amper meter that will measure...

The tubes used for processing in the Whirlwind would end up leading Ken Olson to transistors, which led to the transistorized TX-O (the love of many a tech model railroad clubber) and later to Olson founding DEC. Suddenly, the Whirlwind was the...

A transistor is used to do the heavy lifting, as to protect the Arduino’s relatively low power output (think amplifier power wire on an old car stereo system) and a 12 Volt voltage regulator is used to keep everything tidy. It may get warm but ...

The photo transistor got dirty and needed to be cleaned. Was getting lots of false triggers. Assembly. Take the M5 nut off the v-roller bolt. Insert into the sensor mount. Attach the mount to the back of the sensor. Mount the...

You should keep the diode and capacitor to protect the Nano if you opt to not use the transistor. The speaker can be either an active or passive speaker. When tested both produced similar tones when fed a PMW signal from the Arduino. Which is a good...

Note that if you want to control the PM1006 fan, you will have to add a transistor. Note also that many other designs put the D1 mini inside the case. However, this will impact the temperature measurements, which is why I decided to put the ESP...

It requires 2x1k ohm resistors, and BC547 or similar NPN transistor. Also a 2x6 pin header, and cable to the main board are needed. When using this setup, don't use a transparent flag to block the beam. I had no trouble with sunlight, or an LED...
